HOw to transfer address book (contacts) from Outlook to Outlook Express 6 ?

[Sammy]

I am trying to copy everything from Office Outlook to the
Windows Outlook Express.
The Export function in my Office Outlook does not work.
It requires some installation from the Office XP CD but
fails during installtion. I could easily transfer all the
messages over. Is there a simple way to copy the
contacts (email addresses) over too ?
Thx,
